Theory Quotes
-
By the 'mud-sill' theory it is assumed that labor and education are incompatible; and any practical combination of them impossible. According to that theory, a blind horse upon a tread-mill, is a perfect illustration of what a laborer should be -- all the better for being blind, that he could not tread out of place, or kick understandingly. According to that theory, the education of laborers, is not only useless, but pernicious, and dangerous. In fact, it is, in some sort, deemed a misfortune that laborers should have heads at all.
Abraham Lincoln
-
Words exist only in theory. And then one ordinary day you run into a word that exists only in theory. And you meet it face to face. And then that word becomes someone you know. That word becomes someone you hate. And you take that word with you wherever you go. And you can't pretend it isn't there.
Benjamin Alire Saenz

A study of family portraits is enough to convert a man to the theory of reincarnation.
Arthur Conan Doyle
-
Economists can never be free of from difficulties unless they will distinguish between a theory and the application of a theory.
William Stanley Jevons
-
To despise theory is to have the excessively vain pretension to do without knowing what one does, and to speak without knowing what one says.
Bernard Le Bovier de Fontenelle
-
Evolution is an organizing principle and when we call it a theory, we mean it's a theory, we don't mean that it's a belief that someone holds.
Alan I. Leshner

This whole theory [of John Law and Jean Terrasson], as dear to French financial schemers in the eighteenth century as to American "Greenbackers" in the nineteenth, had resulted, under the Orleans Regency and Louis XV, in ruin to France financially and morally, had culminated in the utter destruction of all prosperity, the rooting out of great numbers of the most important industries, and the grinding down of the working people even to starvation.
Andrew Dickson White
-
I have a theory that, for people of color or others who have been cut out of the master narrative, just telling your personal survival tale, your story, is civic engagement. It is a kind of political performance and is really crucial in that storytelling is how the writers connect with people and change. It's how we collect and add to and complicate the master narrative.
Faith Adiele

A mathematician is a person who can find analogies between theorems; a better mathematician is one who can see analogies between proofs and the best mathematician can notice analogies between theories.

E pur si muove. "Albeit It does move". (That's what Galileo purportedly muttered after torturers forced him to recant his theory that the earth orbits the sun.)
Galileo Galilei
-
You hear the word, and believe it in theory, while you deny it in practice. I say to you, that 'you deceive yourselves'.

Poincaré was a vigorous opponent of the theory that all mathematics can be rewritten in terms of the most elementary notions of classical logic; something more than logic, he believed, makes mathematics what it is.
Eric Temple Bell
-
Qualities I sought in a scientific theory were naturalness, inner perfection and logical simplicity from an aesthetic approach.
Albert Einstein
-
It must be conceded that a theory has an important advantage if its basic concepts and fundamental hypotheses are 'close to experience,' and greater confidence in such a theory is certainly justified. There is less danger of going completely astray, particularly since it takes so much less time and effort to disprove such theories by experience. Yet more and more, as the depth of our knowledge increases, we must give up this advantage in our quest for logical simplicity in the foundations of physical theory.
Albert Einstein
